Chemical Structure
Description
The molecular framework of 5-Chloro-4-fluoro-1,3-dihydro-2,1-benzoxaborol-1-ol (C7H5BClFO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
5-Chloro-4-fluoro-1,3-dihydro-2,1-benzoxaborol-1-ol (CAS 1246632-87-0), molecular formula C7H5BClFO2 and molecular weight 186.38 g/mol, is a CATO reference standard with documented purity and traceability.
